摘要
在给定的混凝土、钢材和钢筋三轴本构关系模型的基础上,应用连续介质力学的方法,对配筋钢管混凝土柱常温下的力学性能进行了分析,导出配筋钢管混凝土柱承载力的理论计算公式,并用文献中的试验结果对公式进行校核,符合良好。
Based on the triaxial stress-strain curves of concrete and steel, the elastoplastic analysis of bar-reinforced concrete filled steel tubular columns is performed and a theoretic calculating formula for the load bearing capability of short columns subjected to axial load at ambient temperature is derived. Good agreement is obtained between the experimental results and the predictions.
